Chapter 7 High-speed Counter Module AH02HC/AH04HC *1: CR0, CR28, CR56, and CR84 can only be used as normal exchange registers. They can not be set by means of the instruction TO. 7.8 Writing Parameters Users can set the parameters in AH02HC-5A/AH04HC-5A by means of ISPSoft, and set CR0/CR28/CR56/CR84 by means of the output devices assigned to AH02HC-5A/AH04HC-5A. The users can also set the parameters in AH02HC-5A/AH04HC-5A by means of the instruction TO or DTO. (1) Software: ISPSoft After AH02HC-5A/AH04HC-5A is installed, HWCONFIG in ISPSoft can be used to set the parameters in AH02HC-5A/AH04HC-5A. Users can not start AH02HC-5A/AH04HC-5A by means of HWCONFIG in ISPSoft.
However, CR0, CR28, CR56, and CR84 can be set by the output devices assigned to AH02HC-5A/AH04HC-5A in the program written in ISPSoft. (2) Instruction: TO or DTO Parameters can be changed by means of the instruction TO or DTO. When AH02HC-5A/AH04HC-5A counts, users can not change parameters.
